Header Specs:

This header is designed for any tube size up to 2 ½” with any collector size up to 5” or our collector mufflers up to a 6” size. All of the tubes are inside the frame with good ground clearance and spark plug access. Our design header was done with the largest tube size available and the bottom of the header was about ¾” below the bottom of a stock oil pan, smaller tube sizes will gain ground clearance. Measuring from the side of a stock oil pan we have 1 ¾” at the top of the pan and 2 ¼” of room at the bottom of the pan on the passenger side with 2 7/8” of room on the driver side for an oil pan sump kick out. With no kick out on the driver side of the pan the oil filter is accessible, but if the pan kick out is under the filter it will be trapped. We designed the header using a Hitachi starter a full size GM starter will not fit. The header will fit side motor mounts or motor plates, but the engine must stay in the stock location.
It will fit Heidt’s inner fender well panels and up to a 9” power brake booster, but is NOT intended for factory style air conditioning, clutch linkage or column shifter linkage.

Header Installation:

We build our race headers with individual tubes and slip on collectors for easier installation. If we are building your header as all one piece in the pro-tour style then the header will have to be installed as the engine is being installed with the steering column removed.
To install the header with individual tubes remove the starter, oil filter, spark plugs and steering column between the 2 “U” joints. On both sides install the tubes from front to back leaving the header bolts loose so the tubes can move freely until all tubes are installed then snug the header bolts, but don’t tighten them until the collectors are installed then go back and tighten all the bolts.
Refer to our header installation tip’s page for additional instructions.
